Measure and mark the location for your trellis by hammering stakes into the ends of the desired trellis rows. Tie string between the stakes to mark the location of the trellis.
Measure the length of your cattle or hog wire panels. Standard panels come in 16-foot lengths.
Place a T-shaped metal fence post into the ground a distance matching the length of your panels along the length of the string marking your trellis location.
Position the cattle panels so that they stand upright against the fence posts. Each cattle panel should touch the fence posts along its ends.
Attach the cattle panels to the fence posts using wire fence fasteners. Your trellis will now be sturdy enough to support the weight of your plants.
